To a/ZZ whom it may concern: A

Be it known, that I, HENRY E. HUGHES, a citizen of the United States,residing at Pawtucket, in the State of Rhode Island, have 'invented anew and useful Improvement in Spindles, of which the cation. p

My invention consists in the employment of antifriction-rollers with'the step for the spindle, as hereinafter fully set forth.

In the accompanying drawings, vligure 1 represents an aXlial section ofthe supporting-case or holder, the bolster, and the step. Fig. 2represents 'a side view of the step removed from the bolster. Fig. 3represents a lower end. view of the same. Fig. 4C represents a sectiontaken on the line 4 et of Fig. 3. Fig. 5 represents a side View of thebolster and step removed from the case or holder.

In the drawings, A represents the spindle, B the whirl, and O thesupporting-case or holder, held in place upon the rail D by meansfollowing is a specifiof the nut E. Within the cavity c. of thesupporting-case C are placed the bolster and step F, the said bolsterand step being made in two parts b and c, the tube c,- which forms thestep, being connected with the tube b, which forms the bolster, by'meansof a joint d and pin e. The screw f passes d'iametrically acrossthe cavity of the tube c, and upon the screw f are place'd theantifriction-rollers g g, the peripheries of `which are so arranged asto form an antifrictional support for the spindie, the squared lower endof the spindle resting thereon, as shown in Fig. 4, and within thecavity of the tube c, above the antifriction-rollers g g, is placed theloose sleeve h, which serves to hold the lower end of the spindlecentrally of the step, so that the said lower `end will bear properlyupon the peripheries of the antifriction-rollers. Notches e' z' are madediametrically opposite each other in the lower end of the tube c of thestep, the

said notches serving to engage thewire j, passing diametrically throughthe cavity of the case C, and thus prevent the bolster and step fromturningwith the spindle, while at the same time the bolster and step areupwardly removable at will from the case. The guiding-sleeve h ispreferably employed, but may be dispensed with, and in that case thebore'of the tube c will be contracted so as to loosely fit the spindleabove the antifriction rollers.

I claim as my inventiona l. The combination of the spindle, and thesupportinghcase, with the step and bolster, the antifriction-rollersarranged at opposite' sides of the axis of the step and bolster, andengaging means, arranged between the step and bolster, and thesupporting-case,where by the step and bolster are made readily removable from the case, and rotation with the spindle prevented,substantially as described.

2. The combination of the spindle, and the supporting-case, with thestep and bolster, the antifriction-rollers arranged at opposite sides ofthe axis of the step and bolster, the guiding-sleeve, and means arrangedbetween the step and bolster, and the supporting-case, for preventingthe rotation of the step and bolster, with the spindle, substantially asdescribed.
